The plot-line of the series is that Drake's mother marries Josh's father, making the two stepbrothers. They are in the same school and grade, but they are complete opposites; Josh is good in school and always well-behaved while Drake gets bad grades and breaks tons of rules. They put up with multiple challenges, many of them including their devious little sister, Megan. The show ran for 4 seasons.

Trivia

Josh Peck, an actor in Drake & Josh, also made an appearance in Wok Star. He plays an audience member who complements Jade on her show, to which Jade replies with "whatever." Jade confirmed on TheSlap that this was, in fact, Josh Peck.

Whether Drake & Josh is a TV show or real life in the Victorious world is a bit unclear because Cat mentioned that she watched an episode of it, however one of the characters from the show, Helen, is a recurring character.

In Jade Gets Crushed, the robot which Beck was taking pictures of in the beginning was used in the Drake & Josh TV show. Dan confirmed this via Twitter: "Who recognized Beck's red ROBOT from @Victorious tonight? It's the ACTUAL ROBOT I used in an episode of Drake & Josh 4 or 5 years ago!"
